Conference Announcement

Inheritance and
Cooperation

June 25th
& 26th, Balliol College Oxford

Heredity is understood to be a core ingredient of evolution
by natural selection, and is standardly thought of as mediated by the passing
of genes from parents to their offspring. Genetic inheritance underpins the
theory of kin selection, which stands as a leading explanation for the
evolution of cooperation. Organisms can be selected to help their relatives,
because those relatives inherited some of the same genes from the common
ancestor. We say that helping relatives then boosts the organism's indirect
fitness. However, cooperation takes place in many scenarios in which there is
no recourse to explanation in terms of indirect fitness benefits, because the
participants lack a common genetic inheritance: between species; between
unrelated humans; between genes; to name a few.

We are becomingly increasingly aware of the action of
systems of inheritance that are not genetic. Organisms inherit, for example,
epigenetic marks, niches, symbionts, culture. We are learning more and more
about non-standard genetic inheritance systems such as lateral gene transfer,
meiotic driver genes and transposable elements.

What happens to our ability to explain the occurrence of
cooperation if we expand our conception of inheritance? Might we throw light on
the possibility of cooperation between partners that fail to share a common
genetic inheritance? Can other inheritance systems play an analogous
explanatory role to that played by genes in kin selection theory? Are all
inheritance systems equal, in this sense, or do they vary in ways that
systematically affect their influence upon cooperation?

The aim of this conference is to pull together people who
research different sorts of inheritance systems, or explore the impact of those
systems on cooperation, to see if anything general can be extracted about the
ways in which inheritance influences cooperation.
